Title: Semiconductor memory
Inventor: TAGAYA MITSUE
IPC: G11C11/401
Filed: 1990-04-27
Abstract: PURPOSE:To prevent the malfunction of sense amplifiers by interposing transistors TRs for switch between a pair of bit lines to electrically separate the pair of bit lines to plural elements and providing sense amplifiers which differentially amplify elements of the pair of bit lines. CONSTITUTION:Plural N-type TRs for switch TR1 to TRn-1 are interposed between a pair of bit lines BA and the inverse of BA, and elements B1A to BnA and the inverse of B1A to the inverse of BnA of the pair of bit lines are arranged in series through these TRs. Elements B1A to BnA and the inverse B1A to the inverse of BnA of the pair of bit lines are provided with sense amplifiers S1A to SnA respectively. Level limiter signals LSW1 to LSWn-1 are inputted from a level limiter switch selecting circuit 1 to gates of TRs TR1 to TRn-1 and these TRs are controlled, and sense amplifiers S1A to SnA are selectively controlled by a sense amplifier selecting circuit 2. Thus, the load capacity to each of sense amplifiers S1A to SnA is reduced to prevent the malfunction of sense amplifiers.

Title: Power supply device
Inventor: SAEKI MITSUO
IPC: H02M7/06
Filed: 1994-05-26
Abstract: PURPOSE:To increase the temperature of a switching diode during operation and to decrease a forward voltage drop by forming a switching diode integrally with the heat generation parts of a power supply device or laying the diode near the heat generation parts. CONSTITUTION:A booster-type DC-DC converter 42, a battery 41, a booster coil L, a transistor Tr for switching, a switching diode D1, etc., are mounted on a substrate 45 and the parts are electrically connected. Then, a power supply voltage is outputted from output lines 46 and 47. In this case, the transistor Tr for switching and the switching diode D1 are constituted in a same package or are formed integrally by adhesion with an adhesive. Since the transistor Tr for switching generates heat, the temperature of the switching diode D1 also increases by accompanying the heat generation of a transformer Tr for switching during operation and forward voltage drop decreases.

Title: Quantitative measurement of cholesterol
Inventor: MIYASHITA YOSHINOBU
IPC: G01N33/92
Filed: 1982-06-29
Abstract: PURPOSE:To carry out diagnosis of various geriatric diseases, by a method wherein cholesterol in a living body specimen is reacted with digitonin and the intensity of diffused light from the formed fine particle is measured to quantitatively measure cholesterol in good preciseness in a reduced amount of the specimen as compared to a nephelometry method. CONSTITUTION:Cholesterol or cholesterol ester is extracted from a living body specimen such as blood by acetone and, after cholesterol ester is hydrolyzed by a KOH solution, the extract is neautralized by acetic acid. One drip of a surfactant (pref., a nonionic one) is added to the neutralized specimen to be well mixed therein. In the next step, 50% ethanol solution of digitonin is added to and mixed in the specimen and, after the mixture is allowed to stand for about 20min at a room temp., the intensity of diffused light of the incident light from a laser source is measured by a laser nephelometer. The surfactant uniformly disperses fine particles of digitonide formed through the reaction of cholesterol and digitonin. The measured value is collated with a calibration curve obtained by using a known amount of cholesterol to measure the cholesterol concn. in the specimen in good preciseness.

Title: Water supply device
Inventor: MORI NORIYUKI
IPC: F04D15/00
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of water failure caused by droppage of pressure inside an accumulator to zero by arranging a retarding mechanism between the accumulator and a water supply pipe of a deep well underwater pump, for retarding pressure fall inside the accumulator and regulating water supply from the accumulator to a specified value. SOLUTION: An accumulator 20 is connected to a water supply pipe 17, at its position on a downstream side of the portions to which pressure sensors PS1, PS2 are connected, through a check valve 19 having retarding function for regulating water supply amount from the accumulator to a specified value and retarding pressure fall of the accumulator. In the case that the water supply amount from the accumulator 20 is regulated to ten and several liters/mm or more by means of the check valve 19 having retarding function and suspended there, the pressure in the water supply pipe 17 is abruptly dropped to starting pressure PS2. Pressure fluctuation time is thus shortened because acceleration is started during deceleration upon inverter controlling. Even when a faucet is opened largely during stoppage of a pump, occurrence of water failure is prevented.

Abstract: PURPOSE:To look at an actual view of an area to which the direct viewing is impossible and to detect early a processing mistake, by supplying the video data from an external controller like a video camera, etc. and displaying selectively the signal information to a display device of an NC device. CONSTITUTION:When a switch 15 is kept off, a control part 3 gives an indication to a data signal switching part 14 to turn on an area between an output interface 6 and the part 3. Thus the display data given from the part 3 having a CPU at the side of an NC main body 1 is applied to a display device 9 via the interface 6. Then the information on the side of the main body 1 is displayed. When the switch 15 is turned on, the part 3 reads out an additional program 16 for switching and sends a picture data selection signal to a data signal switching part 14. Thus the part 14 turns off an area between the part 3 and the interface 6 and at the same time turns on an area between an input interface 13 and the interface 6. Then the picture data is validated and the images of a video camera 12 are displayed to the device 9.

Filed: 1977-09-19
Abstract: PURPOSE:To shorten both memory access time and memory cycle time by discriminating a command supplied via the same command line so that when it is a read command, a read operation will be done and when a write command, a write operation will be done. CONSTITUTION:Arithmetic controller 1 supplies at least a read command, write command and command to a register to memory unit 2 via the same command line. In this case, command discrimianting method 11 discriminates the command, and in parallel to it, reading method 13 starts to operate the reading to memory part 2. When the discrimination result by command discriminating method 11 is a read command, the reading is continued and when a write command, the write operation to register 9 is started. Consequently, the memory access time and memory cycle time both can be shortened.

Filed: 1979-09-03
Abstract: PURPOSE:To provide a solder alloy having a predetermined compsn. consisting of tin, zinc and Bi which alloy is harmless to the human body and exhibits high strength and work efficiency. CONSTITUTION:The solder alloy consists of tin 65-75wt%, Bi 3-9wt% and the balance zinc. In case inner wire 3 is put into hole 2 of metal fitting 1 and soldered with this solder alloy, this solder well attaches to the outside of fitting 1 and penetrates into the space between wire 3 and fitting 1 because of its high fluidity and wettability. When the soldered fitting is pulled up from molten solder A in vessel 4, incicle-form hanging solder 5 or fitting 1 surface gob 6 is not left. In the soldering the drawing strength of fitting 1 from wire 3 is 125kg or more, and a change with the passage of 500hr includes nothing more than a lowering of about 4% in the drawing strength. These results are very excellent compared to conventional lead- tin solder, etc.
